Key take-away

It was previously unclear whether the Belgian tax authorities would require a daily assessment of the net interest position of a cash pool for thin cap purposes. The Minister of Finance now confirms that his administration is willing to consider on a case-by-case basis more practical approaches based on averages.

No further guidance is given as regards the specific cases that would qualify for a more lenient approach or how the averages would then be calculated in practice.
